sPARK-EJECTOR FOR Locolvlorlvss.

SPECIFICATION forming part Of Letters' Patent N0. 281,160, dated. July10, 1883. Application filed March Q2, 1883. (No model.)

To @ZZ whom it 11mg/ concern:

Be it lknown that I, JAMES K. TAYLon, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful 'Improvements in Spark-Ej ectorsfor Locomotives; and-I do hereby declare that the same are fullydescribed in the following specification and illustrated in theaccompanying drawings. Y

This invention relates to the discharge of arrested cinders and sparksaccumulated in the sm oke-arch or extension-reservoir of a locomotive.The object is to eject the particles from said reservoir or arch bymeans of a jet of hot water or steam fromr the boiler, or of compressedair from the air-drum, aided by a stirring apparatus, both acting whenthe locomotive is in motion or at rest; and in order to prevent delaysarising from stopping to discharge after running a long distance andfillingthe reservoir with sparks and dust, they may be discharged bythis mechanism While the engine is running at full speed. The wholeapparatus is designed to be Worked by the engineer from his place in thecab.

My invention consists in the devices and combinations of devices setforth in the appended claims.

In the drawings, Figure l is a longitudinal section of part of alocomotive to which my Fig. 2 is a front elevation, partly in section.Figs. 3, 4, and 5 are detail views of the improvements, seen from theside, front, and top, respectively; and Figs. 6 and 7 are enlarged viewsof the cylinder and hollow piston and of the gate moved thereby.

The locomotive is provided with a suitable deflector and with pipeleading the arrested sparks to the spark-reservoir A. At the bottom ofthis reservoir there is bolted a cylindrical shell, B, having at eachside a dischargepipe, B, preferably cast integral with it. Within thisshell is a cylindrical gate, C, closed at the bottom and provided in itsvertical wall with two apertures, C', corresponding in size and shapewith the inner diameter ofthe discharge-pipes B. The gate C has asemi-rotary 5o movement Within the shell B, and the apertures C are solocated as by such movement to be each brought separately before one ofthe pipes B for discharge of the accumulated cinders and sparks 5 but inthe normal position of this gate both the apertures are closed by theinner wall of the shell B. The gate may be properly supported by lugs D,bolted to projections B of the shell, and extending inwardly therefrombeneath the gate, so that by removal of thebolts and lugs the gate C maybe removed and replaced vertically from beneath the shell B.

The mechanism shown for giving to the gate C its partial rotary movementis novel. A segment-gear, G, cast with or secured to the lower end ofthe gate meshes with the teeth of Aa straight rack, H, on asteam-cylinder, I, which hasareciprocating motion on a straight andhollovT piston-rod, J, having a fixed piston,-r K, at its center. Thepiston-rod J. is mounted securely in brackets F, and extends across thefront of the engine. It is plugged atthe center, where the piston isiixed in its position. Steam or compressed air is admitted to anddischarged from each end of the cylinder I alternately, through holes Jin the rod J, by means of a pipe, T, at each end ol' said rod, providedwith suitable cocks located in the cab of the engine. A guide-rod, M,prevents the cylinder from rotation on the piston-rod J, and keeps thegear and rack in engagement. It is obvious that other suitable means maybe employed to operate the gate-- such as a lever andlink-conncction-if'preferred.

'Ihe movement of the cylinder I to one end of the hollow piston-rodturns the cylindrical gate C so as .to bring one of its apertures C tocoincide with one of the pipes B', and if the water, air, or steam jetis now turned on, a rapid discharge of the cinders or sparks in thereservoir will follow, and continue during the pleasure of the engineer,until all are ejected. Should it be desired to ei ect them on theoppo'site side of the track, the steam is shut oft' 'from the end of thehollow piston-rod firstemployed and turned on at the other end, carryingthe cylinder I also to the other end, since its piston cannot move underthe steam-pressure; and this movement of the cylinder rotates IOO -whichthe cinders willv be blown.

In order to insure a free discharge of the accumulated cinders, Iprovide an agitator having a vibratory or rocking movement withf in thereservoir or gate, and working in bearings, so that it may be actuatedfrom the cab by convenient means. As represented in the drawings, theagitator N has three pairs of projecting prongs mounted on a squarecentral shaft, O, having horizontal bearings P in the upper part of theshell B. One pair of these prongs extends down into the center of thegate, while the others run upwardly. The shaft is oscillated by a lever,Q, worked by a connecting-rod, vR, a steam or air cylinder, S, or byother suitable means.

I claim as my inventionl. In a locomotive havinga receptacle forarrested sparks, an ejector provided with a rotating. gate havingydischarge-openings, a blast-pipe leading thereto, and suitable means ofoperating the same, substantially as and for the purpose set forth.

2. In a locomotive having a receptacle for arrested sparks, an ejectorhaving two lateral openings at the base of said receptacle, a stea'mpipeleading to each opening, Vand a rotating` gate having twodischarge-passages adaptedto be brought successively before suchopenings, for the purpose set forth.

3. A sparleejectorhaving a rotary gate prcvided with a gear, incombination with a reciprocating cylinder having a rack engaging withsaid gear, vwhereby the gate is partially rotated, for the purpose setforth.

4; An agitator mounted in bearings at the base of the spark-reservoir,and adapted to be operated by a crank or lever, for the purpose setforth.

5. The combination of the spark reservoir and ejector with an agitatoradapted to be operated from the cab of the locomotive, for thepurposeset forth.

In testimony whereof I hereto affix my signature in presence of twowitnesses.

JAMES TAYLOR.
